Module G: Interactive FAQ
Which tax regime is better for me – old or new?
The choice depends on your income level and eligible deductions:
- Income ≤ ₹7.5 lakh: New regime is usually better due to full rebate under Section 87A
- Income ₹7.5-15 lakh: Compare both regimes based on your 80C investments
- Income > ₹15 lakh: New regime often wins due to lower surcharge rates
- With significant deductions: Old regime may be better if you have >₹2.5 lakh in deductions
Use our calculator to compare both regimes with your specific numbers. According to PRS Legislative Research, about 87% of taxpayers with income above ₹1 crore now opt for the new regime.
How is the standard deduction of ₹50,000 applied in both regimes?
The standard deduction works differently:
- Old Regime: Available since FY 2018-19, replaces transport allowance (₹19,200) and medical reimbursement (₹15,000)
- New Regime: Introduced in Budget 2023, this is the only deduction allowed (along with family pension deduction)
- Calculation: Flat ₹50,000 reduction from gross income before calculating taxable income
- Eligibility: Available to both salaried individuals and pensioners
Note: In the new regime, you cannot claim additional deductions like HRA or LTA if you claim the standard deduction.
What are the key differences between old and new tax regimes?
| Feature | Old Tax Regime | New Tax Regime |
|---|---|---|
| Introduction Year | Pre-2020 | Budget 2020 (Modified 2023) |
| Default Option | No (must opt-in) | Yes (from FY 2023-24) |
| Tax Slabs | 3 slabs (5%, 20%, 30%) | 6 slabs (0% to 30%) |
| Basic Exemption | ₹2.5L (₹3L for seniors) | ₹3L for all |
| Deductions Allowed | Full deductions (80C, 80D, HRA etc.) | Only standard deduction (₹50k) |
| Rebate (87A) | Up to ₹5L income | Up to ₹7L income |
| Surcharge Rates | 10-37% (same as new) | 10-37% (but lower marginal rates) |
| Best For | Those with high deductions | Those with low deductions |
The new regime is particularly beneficial for those who don’t have significant investments or expenses that qualify for deductions under the old regime.
How are capital gains taxed under both regimes?
Capital gains taxation remains the same regardless of which income tax regime you choose:
- Short-Term Capital Gains (STCG):
- Equity/Equity MF: 15% if sold within 1 year
- Debt/Other assets: Added to income, taxed at slab rate
- Long-Term Capital Gains (LTCG):
- Equity/Equity MF: 10% on gains >₹1 lakh (no indexation)
- Debt/Property: 20% with indexation benefit
- Grandfathering: LTCG on equity up to 31/01/2018 is exempt
- Set-off Rules: STCG can be set off against any capital gains; LTCG only against LTCG
Example: If you sell shares purchased at ₹10,000 and sold at ₹15,000 within 6 months:
- STCG = ₹5,000
- Tax = 15% of ₹5,000 = ₹750 (same in both regimes)
Can I switch between tax regimes every year?
Yes, you can switch between regimes every financial year with these conditions:
- Salaried Individuals: Must inform employer at the start of FY (Form 10IE)
- Business/Profession: Can choose regime for each FY when filing ITR
- First Time: Default is new regime; must opt for old regime if preferred
- Deadline: Choice must be made before filing return for that FY
- Exception: If you have business income, you can only switch once in lifetime (from old to new)
According to Income Tax e-Filing portal, over 60% of taxpayers switched to the new regime in FY 2022-23 after comparing both options.
How does the calculator handle surcharge and cess?
Our calculator automatically applies surcharge and cess based on these rules:
- Surcharge Calculation:
- 10% for income between ₹50 lakh to ₹1 crore
- 15% for ₹1 crore to ₹2 crore
- 25% for ₹2 crore to ₹5 crore
- 37% for income above ₹5 crore
- Cess Calculation:
- 4% Health & Education Cess on (Income Tax + Surcharge)
- Example: For ₹10 lakh tax + ₹1 lakh surcharge = ₹11 lakh × 4% = ₹44,000 cess
- Marginal Relief:
- Provided when income slightly exceeds surcharge thresholds
- Ensures surcharge doesn’t make tax liability higher than the threshold difference
- Display in Results:
- Surcharge shown as separate line item
- Cess shown as separate line item
- Total tax = Income Tax + Surcharge + Cess
The calculator uses precise marginal relief calculations to ensure accuracy at threshold points, following Department of Revenue guidelines.
